What is a Drill Chuck:
Generally a chuck is a specially designed clamp which is used to hold any object with radial symmetry.
A drill chuck is the specialized, self- centering chuck, used to hold the drill bits in the place. Inside of a chuck, there are three jaws which you can open or close. Depending on direction, you need to rotate the sleeve of your chuck.
A drill chuck key is the small, ridged tool that fits in the grooves of your drill chuck so that you can tighten or loosen the chuck if needed. Almost every drill machine has its own chuck key to open and close the chuck for replacing the bit. While installing a new bit, place the key into the center of the chuck’s jaw.
